Tooll, whom it may concern.- i

. Be it knownfthat 1, SIMEON O. LAWLOR, a

citizen of the United States, residing at'Dnlnth, in the county of St. Louis and State of Minnesota, have invented certain new andv useful Improvements in Window-Washing Apparatus 5 and I do hereby'declare'the'following to be a full, clear, and exact description of the'invention, such as will enable otht0 ers skilled in the art to which it appertains to make and use. the same. I This invention relates to improvements in window-cleaners, and particularly to" that class of such devices by means of which the outer surfaces of the window may be cleaned by a person operating inside or the house, whereby ,the exposure anddanger of falling fromthe window-sill is avoided, the'object of the invention being to provide an improved 2o device of this class by which .the desired operations may be performed in the least possible timeand with the least possible expenditureof labor. y I

With this object in view the invention consists in an improved window-cleaner of the class mentioned, theconstruction, arrangement, and combination of the parts of which will be hereinafter fully described and afterward specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view through a windowwasherconstructed in accordance with my invention, the section being taken on the plane indicated on the line 1 1 of Fig. 2.. Fig. 5 2 is a vertical section through the same on a plane at right angles to that of Fig. 1 and parallel with a window-pane, as indicated by the broken line 2 2, Fig. 1. Fig.3 is a detail perspective view of the swi veled carriage. 4o Like numerals of reference mark the same parts wherever they occur in more than one view of the drawings. Referring to the drawings by numerals, 4 indicatesa hollow vertical standard, which 4 5 in the actual operationof the device stands outside of the window. This standard may. or may not be closed at the bottom, as shown, and is provided with" a pulley 5, journaled. in notches or slots at its upper end.

a suitable handle 15.

a position within ready reach ofthQhfilldrOf I 16 indicates a horizontal tube'ada'pted be secured between the sidesof the windowsill of the window. This bar or tube 16 is socured in such position by meanslof springs 17, bearing at their inner ends against a plug frame, as at 17, below and parallelwith the bottom bar'of the window-sash and near the "20, which are provided with rou'ghehed'or padded heads 21 to bear against thOrSldGS of thewindow' frame, nuts 22 being provided on the threaded bars to tighten them in position.

Upon the tube 16 is mounted a carriage 23, in this instance consisting ofa hollow or tubular structure, carrying on its lower side a'projec- 'tion 24:,havin g a fiat-lowerface. 'Swiveled to." thecarriage 23 is a block 25, having its upper. .face flattened to engage the flat lower faceof' the projection, 24:, before mentioned, and free to turn on thswiveling pin 26. This block' 25 is bored to receive the tube 14:, before mentioned,-which't nbe is secured therein at any desired positionby a set-screw 27 or other suitable means.

In the operation of the vdevice when the" parts are adjusted as before described the operator within the room by drawing inward on the cord 10 causes the block 7 to slide downward on the vertical standard 4, drawing the brush or cleaner 8 downward on the pane 9 oi: the window. Upon the release of the cord the rubber cord or tube 6 by its elasticity causes the block 7 to slide upward on the standard 4, thus moving the brush or cleanerv 8 upward on the window-pane. The carriage 10 23 being movable horizontally on the tube 16,

aall parts of the window-pane, and especially to clean any slight strip which mayhave been left between the portions of the pane cleaned during each lateral adjustment of the washing mechanism on the tube 16.

llhe prouision of the rubber cord or tube 6 is of special importance, for the reason that the material thereof is ndt subject to damage by moisture, as would be a metal spring, and for the further reason that the structure is simplified and cheapened, the r u bber cord or tube serving both as a spring to return the block7 upward and also as a cord to properly work over the pulley 5. v

' I make no. specific claim under this application to the construction of the coupling, which is fixed upon the vertical standard and receives and holds the laterally-movable horizontally-extending window-washing rod, nor

do I make any specific claim under this ap- 4o plication to the construction and arrangement of the carriage carrying the horizontally-extending laterally-movable wiudowwashing rod, as the same are made the subject of an applic'ation filed by me on the 26th day of June, 1900, Serial No; 21,699.}

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is,

1. In a window-washer, the combination of a horizontal tube adapted to be rigidly secured betweenthe sides of the window-frame, of a carriage mounted to slide on said tube, a block swiveled to said carriage, a horizontal tube or bar mounted in said swiveled block, a vertical standard carried by the horizontal tube or bar, and washing devices carried by the vertical standard, substantially as described. j

2. In a window-washer, the combination of a vertically-arranged hollow standard, a pulley-mounted at the upper end thereof, a block slidably secured on the outside of the standard and carrying a window brush or cleaner which always remains outside of the standard, an elastic cord fixedly secured at or near the lower end of the standard and extending upwardly therefrom along said standard and passed over the pulley and secured to the under side of the blockfor automatically raising said block and the brush or cleaner carried thereby each time they are drawn downwardly by the operator, and. an inelastic cord secured-to the under side of the block and extending to a suitable point within easy reach of the operator for drawing the block downward on the standard, substantially as described.
